Ak'u nahane ka senohe se bolella batsoali ba hao, letsatsing leo u hlahileng ka lona, ​​hore na u tla phela nako e kae. Phihlelo e tšoanang e ka etsahala bakeng sa litsebi tsa lik'hemik'hale tsa betri tse sebelisang mehlala e mecha ea lik'homphieutha ho bala nako ea bophelo ba betri ho latela potoloho e le 'ngoe feela ea data ea liteko.

Phuputsong e ncha, bafuputsi ba Lefapha la Matla la US (DOE) Argonne National Laboratory ba retelehetse matleng a ho ithuta ka mochini ho bolela esale pele bophelo ba mefuta e mengata ea lik'hemik'hale tse fapaneng tsa betri. Ka ho sebelisa lintlha tsa liteko tse bokelletsoeng Argonne ho tsoa sete ea libeteri tse 300 tse emelang lik'hemik'hale tse tšeletseng tse fapaneng tsa betri, bo-rasaense ba ka fumana ka nepo hore na libeteri tse fapaneng li tla tsoela pele ho potoloha halelele hakae.

Bafuputsi ba Argonne ba sebelisitse mehlala ea ho ithuta ka mochini ho etsa likhakanyo tsa bophelo ba potoloho ea betri bakeng sa mefuta e mengata ea lik'hemik'hale tse fapaneng. (Setšoantšo ke Shutterstock/Sealstep.)

Ka hara algorithm ya ho ithuta ka mochini, bo-rasaense ba koetlisa lenaneo la khomphutha ho etsa diphetho hodima sete ya pele ya data, ebe ba nka seo ba ithutileng sona thupelong eo ho etsa diqeto hodima sete e nngwe ya data.

“Bakeng sa mofuta o mong le o mong o fapaneng oa ts'ebeliso ea betri, ho tloha lifonong tsa selefounu ho ea likoloing tsa motlakase ho ea polokelong ea gridi, nako ea bophelo ba betri ke ea bohlokoa haholo bakeng sa moreki e mong le e mong,” ho boletse rasaense oa lik'homphieutha oa Argonne Noah Paulson, mongoli oa phuputso eo. “Ho tlameha ho potoloha betri ka makhetlo a likete ho fihlela e hloleha ho ka nka lilemo; mokhoa oa rona o theha mofuta oa kichine ea teko ea lik'homphieutha moo re ka tsebang kapele hore na libeteri tse fapaneng li tla sebetsa joang.”

“Hona joale, tsela feela ea ho lekola hore na matla a betri a fela joang ke ho potoloha betri,” ho eketsa Argonne electrochemist Susan “Sue” Babinec, mongoli e mong oa phuputso eo. “E theko e boima haholo 'me e nka nako e telele.”

Ho ea ka Paulson, mokhoa oa ho theha bophelo ba betri o ka ba boima. "Nnete ke hore libeteri ha li tšoarelle ka ho sa feleng, 'me hore na li nka nako e kae ho latela tsela eo re li sebelisang ka eona, hammoho le moralo oa tsona le k'hemistri ea tsona," o boletse joalo. "Ho fihlela joale, ha ho so be le mokhoa o motle oa ho tseba hore na betri e tla nka nako e kae. Batho ba tla batla ho tseba hore na ba na le nako e kae ho fihlela ba tlameha ho sebelisa chelete ho betri e ncha."

Karolo e 'ngoe e ikhethang ea thuto ke hore e itšetlehile ka mosebetsi o moholo oa liteko o entsoeng Argonne holim'a mefuta e fapaneng ea lisebelisoa tsa cathode tsa betri, haholo-holo cathode e thehiloeng ho Argonne e nang le patente ea nickel-manganese-cobalt (NMC). "Re ne re e-na le libeteri tse emelang lik'hemik'hale tse fapaneng, tse nang le litsela tse fapaneng tseo li neng li tla senyeha le ho hloleha ka tsona," ho boletse Paulson. "Boleng ba thuto ena ke hore e re file matšoao a khethollang hore na libeteri tse fapaneng li sebetsa joang."

Phuputso e 'ngoe sebakeng sena e na le monyetla oa ho tataisa bokamoso ba libeteri tsa lithium-ion, ho boletse Paulson. "E 'ngoe ea lintho tseo re khonang ho li etsa ke ho koetlisa algorithm ho k'hemistri e tsejoang le ho e etsa hore e etse likhakanyo ho k'hemistri e sa tsejoeng," o boletse joalo. "Ha e le hantle, algorithm e ka re thusa ho re lebisa tseleng ea lik'hemistri tse ncha le tse ntlafalitsoeng tse fanang ka bophelo bo bolelele."

Ka tsela ena, Paulson o lumela hore algorithm ea ho ithuta ka mochini e ka potlakisa nts'etsopele le liteko tsa lisebelisoa tsa betri. "A re re u na le thepa e ncha, 'me u e potoloha ka makhetlo a 'maloa. U ka sebelisa algorithm ea rona ho bolela esale pele nako ea eona ea bophelo bo bolelele, ebe u etsa liqeto tsa hore na u batla ho tsoela pele ho e potoloha ka liteko kapa che."

“Haeba u mofuputsi laboratoring, u ka fumana le ho leka lisebelisoa tse ling tse ngata ka nako e khuts'oane hobane u na le mokhoa o potlakileng oa ho li hlahloba,” ho eketsa Babinec.

Pampiri e thehiloeng thutong ena, "Boenjiniere ba likarolo bakeng sa ho ithuta ka mochini bo nolofalitse ho bolela esale pele nako ea bophelo ba betri esale pele,” e hlahile khatisong ea inthanete ea la 25 Hlakola ea Journal of Power Sources.

Ntle le Paulson le Babinec, bangoli ba bang ba pampiri ena ba kenyelletsa Joseph Kubal oa Argonne, Logan Ward, Saurabh Saxena le Wenquan Lu.

Phuputso ena e tšehelitsoe ka thuso ea Argonne Laboratory-Directed Research and Development (LDRD).
